I've not posted changelogs for today's update as there will be more updates for Android 15 fixes as they come including another update today/tomorrow. Would spam the feed.

Most users will not get the Android 15 updates yet as it is exclusive to Alpha release channel so testers can provide feedback on fixes with AOSP bugs.

Some improvements also need to be made to Private Space. It needs to be worked on further to be more useable to GrapheneOS users, like an install available apps feature similar to user profiles. Private Space was only designed for installing apps from the OS source so it ends up opening the GrapheneOS App Store or Play Store for now, would need to get APKs manually, may be a problem to some.

Private Space also can't transfer files from Owner to Private Space (other way around is fine) which is a regression. Additional work needs to be done.

Here is how the Private Space feature looks so far. This footage belongs to tuxsudo, a Cake Wallet contributor.

Check out his thread for more, note this is footage from a sideload-only pre-Alpha build of GrapheneOS and regressions in this thread have or are currently being addressed in following updates. If you are a normal user then you do not have this feature yet.
